Switch
A device that directs electricity, or light, along different physical paths.
Switches act as the center of a "star" topology, much like hubs. They have between 4 and 20+ ports. Internally, switches are different that hubs due to their intelligent design. Switches "remember" what device is attached to what port, and will relay packets only to the proper Destination port. Because of this, all devices attached are able to utilize their maximum rated speed, be it 10 or 100Mbit/sec/port. This cleaver design makes switches more expensive, but in a busy network, switches can keep the traffic flowing.
